WARNING THIS ANTENNA IS AN ELECTRICAL CONDUCTOR. CONTACT WITH POWER LINES CAN RESULT IN DEATH, OR SERIOUS INJURY. DO NOT INSTALL THIS ANTENNA WHERE THERE IS ANY POSSIBILITY OF CONTACT WITH HIGH VOLTAGE OR ARC-OVER FROM POWER CABLES OR SERVICE DROPS TO BUILDINGS. THE ANTENNA, SUPPORTING MAST AND/OR TOWER MUST NOT BE CLOSE TO ANY POWER LINES DURING INSTALLATION, REMOVAL OR IN THE EVENT PART OF THE SYSTEM SHOULD ACCIDENTALLY FALL. FOLLOW THE GUIDELINES FOR ANTENNA INSTALLATIONS RECOMMENDED BY THE U.S. CONSUMER PRODUCT SAFETY COMMISSION AND LISTED IN THE ENCLOSED PAMPHLET.
Your Cushcraft R8 vertical antenna is designed and manufactured to give trouble free service. This antenna will perform as specified if the instructions and suggestions in this manual are followed and care is used in the assembly and installation. When checking the components received in your antenna package use the parts listed beside each diagram. There is a master parts list on page 2. If you are unable to locate any tube or component, check the inside of all tubing. IMPORTANT: Save the weight label from the outside of the carton. Each antenna is weighed at the factory to verify the parts count. If you claim a missing part, you will be asked for the weight verification label. PLANNING Plan your installation carefully. If you use volunteer helpers be sure that they are qualified to assist you. Make certain that everyone involved understands that you are the boss and that they must follow your instructions. If you have any doubts at all, employ a professional antenna installation company to install your antenna. LOCATION Although the R8 will operate in almost any location, it will perform best if it is mounted vertically and located in the clear away from surrounding objects such as buildings, trees, power lines, towers, guy wires, antennas and metallic objects. EXTREME CARE MUST BE USED FOR YOUR SAFETY. YOU MUST INSURE THAT WHILE THE R8 IS IN OPERATION NEITHER PEOPLE NOR PETS CAN COME IN CONTACT WITH ANY PORTION OF YOUR ANTENNA INCLUDING THE COUNTERPOISE RODS. DEADLY VOLTAGES AND CURRENTS MAY EXIST. ALSO, SINCE THE EFFECTS OF EXPOSURE TO RF ARE NOT FULLY UNDERSTOOD, LONG TERM EXPOSURE TO INTENSE RF FIELDS IS NOT RECOMMENDED. THERE ARE SEVEN WARNING STICKERS WHICH MUST BE ATTACHED TO THE ENDS OF THE COUNTERPOISE RODS AS SHOWN IN FIGURE E. MOUNTING Your mast should be rigid and pointing straight up. Always use a mast at least 1-3/4 inches (4.4 cm) but not larger than 2-1/8 inches (5.4 cm) in diameter. If you guy the mast, use nonconducting guy wires. SYSTEM GROUNDING Direct grounding of the antenna mast is very important. This serves as protection from lightning strikes and static buildup, and from high voltages which may be present in the equipment attached to the antenna. A good electrical connection should be made to one or more ground rods directly at the base of the antenna or mast using a least #10 AWG ground wire and noncorrosive hardware. For details and safety standards, consult the National Electrical Code. You should also use a coaxial lightning arrestor. Cushcraft offers several different models, such as the LAC-1, LAC-2 or the LAC-4 series. ASSEMBLY Assemble your R8 by following steps 1 through 12. After assembling the antenna, verify all dimensions for accuracy.

Make sure that the slotted end of (SA) tube protrudes beyond the 4-hole insulator and the opposite end of (SA) tube is mounted flush with the bottom of the stub clamp (see callout at bottom of Fig I). In same fashion slide the tube (SC) and secure it on other side of bottom aluminum stub clamp. Align the bottom stub clamp with plastic insulators and secure it tight. Slide the 6" rod (SB) into tube (SA) and secure with worm clamp (407). Use 6 Meter tuning chart to adjust the stub (SB) for selected portion of the band. Place the protective plastic cap on top of (SB) tuning rod to complete the 6 Meter stub.

First attach the mounting plate (4079) with U-bolts (404), aluminum V-blocks (63), and nut (389) to the antenna base. The bottom of the plate should should be even with the bottom of the antenna to leave room for the radial clamping system. Affix danger label (326) to the antenna so that is easy to see. When attaching mounting plate to the mast use the (405) U-bolts, aluminum V-blocks (63), and nut (389).

Figure N
#12 - FEEDLINE The R8 is designed for use with 50 Ohm coaxial cable terminated with a PL-259 connector. The shortest length of cable will have the least loss. A connector boot is included for use with your new antenna (figure O). Slide the boot over the cable before attaching your PL-259. Coat only the outside connector threads and shell with silicone grease. Do not coat the center pin or receptacle. After the PL-259 is firmly screwed onto the antenna connector, slide the vinyl boot over the connector and against the connector bracket for a good weather-tight connection. After the antenna is on the mast, tape the feedline to the mast. If you plan to install the antenna in a salty or corrosive environment, you may want to consider coating it with a clear marine varnish or equivalent after it is assembled.
